baylyi genome. Lower: Researchers engineered A. baylyi to find the mutated KRAS gene, which helps colorectal cancers grow. Detection of tumor DNA activated an antibiotic resistance gene to confirm ...

CATCH technology engineers cells to detect and discriminate cell-free DNA. This may be of value in clinical (cancer and infection) and commercial (ecology, industrial) applications – wherever ...

Instead of turning on an antibiotic resistance gene when they sense tumor DNA, for example, the bacteria could be engineered to turn on production of a genotype-specific small-molecule therapeutic, ...

Researchers from Columbia University have engineered ... bacteria to target these cancer-specific mutations, we can create more effective therapies that prompt a patient's immune system to detect ...

Just colorectal cancer — often arising ... a specific strain of the bacteria Escherichia coli produces a toxic molecule, called colibactin, which damages the DNA of human cells.
